The claude-agent-sdk's message parser raises MessageParseError for unrecognised message types like rate_limit_event. This causes the entire request to fail with 'Unknown message type: rate_limit_event'. Instead of letting the error propagate, catch MessageParseError during response iteration and skip the unknown message, allowing the rest of the response (including the actual result) to come through. Fixes RichardAtCT#70

Problem
The
claude-agent-sdk's message parser raisesMessageParseErrorfor unrecognised message types likerate_limit_event. Sincereceive_response()yieldsparse_message(data)without catching this error, it propagates up and kills the entire request with:This affects users on Claude Max/Pro subscriptions where rate limit events are sent inline during streaming.
Fix
Wrap the response iteration in
sdk_integration.pyto catchMessageParseErrorand skip unknown message types rather than failing the entire request. The actual assistant response and result message still come through normally.Testing
Tested on a production deployment with Claude Max subscription — responses now complete successfully with rate limit events silently skipped.
